Rabiner and schafer digital speech processing pdf


It is commonly used for searching a long signal for a shorter, known feature. For a large number of samples, the average converges to the true cross-correlation. For image-processing applications in which the brightness of the image and template can vary due rabiner and schafer digital speech processing pdf lighting and exposure conditions, the images can be first normalized.

NCC is similar to ZNCC with the only difference of not subtracting the local mean value of intensities. Caution must be applied when using cross correlation for nonlinear systems. In certain circumstances, which depend on the properties of the input, cross correlation between the input and output of a system with nonlinear dynamics can be completely blind to certain nonlinear effects.
